New dimensions in diseases affecting waterfowl New dimensions in diseases affecting waterfowl
We start off with light heart, but as we near the marsh, we stop abruptly in shock and horror. The shoreline, where only last evening we saw thousands of sleek, apparently healthy birds, is now littered with their bodies. Most of them are ducks, but here and there we see a Canada goose, a gull, an avocet, a black-necked stilt, a pelican..... This is the way Jensen and Williams (1964)...

Orange material in the Sulpicius Gallus formation at the southwestern edge of Mare Serenitatis Orange material in the Sulpicius Gallus formation at the southwestern edge of Mare Serenitatis
Orange and red materials were observed and photographed in the dark mantle of the Sulpicius Gallus Formation on the southwestern rim of the Serenitatis basin. These materials occur only within the dark mantle that overlies old rilled mare and highland units and are absent on the younger mare unit in this area. Orange and red materials occur predominantly as halos, patches, or rays around...

Oil shale development and its environmental considerations Oil shale development and its environmental considerations
The petroleum shortage recently experienced by many nations throughout the world has created an intense interest in obtaining new and supplemental energy sources. In the United States, this interest has been centered on oil shale. Any major action by the federal government having significant environmental effects requires compliance with the National Environmental Policy Act of 1969...

Bidding and production relationships for federal OCS leases: Statistical studies of wildcat leases, Gulf of Mexico, 1962, and prior sales Bidding and production relationships for federal OCS leases: Statistical studies of wildcat leases, Gulf of Mexico, 1962, and prior sales
The relationships between bids received on wildcat leases issued on federal OCS lands in the Gulf of Mexico from 1954 through 1962 and subsequent drilling on, production from, and relinquishment of these leases were studied. The results provided quantitative answers to questions regarding bidding as prescribed by current laws and regulations. Perhaps the most notable result is the...

Mapping of the 1973 Mississippi River floods from the Earth Resources Technology Satellite (ERTS) Mapping of the 1973 Mississippi River floods from the Earth Resources Technology Satellite (ERTS)
On March 31, and May 4 and 5, 1973, the first Earth Resources Technology Satellite (ERTS-1) obtained multispectral scanner imagery over the Mississippi River below St. Louis, Missouri. The river was in flood, and the ERTS data provided the first opportunity for regional synoptic mapping of the extent of flooding at the time the imagery was obtained along a 1200 river-mile reach and some...
